ELECTRIC-LIGHTING ATTACHMENT FOR GAS-BURNERS.

SPECIFICATION forming part of Letters Patent No. 544,634., dated August 13, 1895.

Application filedMarch 11,1896. Serial No. 541,315. mammal To all whom it may concern:

Be it known that I, FRANK A. WEBB,a citi- Welsbach gas-burner provided with my electrio-lighting device. Fig. 2 represents a 1ongitudinal section of the same, partly shown in elevation. Fig. 3 represents a cross-section on the line 3 3 in Fig. 1, and Fig. 4 represents a similar section showing the wire-netting'of the burner removed.

Similar letters refer to similar parts wherever they occur in the different parts of the drawings.

In the drawings, A represents the usual gas-pipe having air-inlets A A, as is common in what is known as a Welsbach incandescent gas-light, having the suspended incandescent mantle B, chimney O, and socket or chimney-support D, as is usual in this kind of light.

E is the burner-tip attached to the upper end of the gas-pipe A, and provided at its upper end with a cup-shaped burner-cap e, over which is fitted the burner F, having its upper end made of wire gauze or netting f, as shown in the drawings.

F F are side perforations in the burner F, as shown in Figs. 1 and 2, through which air is admitted to the burner.

Within the cap 6 are arranged a stationary and a movable electrode, as follows: G represents the stationary electrode, which is secured in an insulated manner to the cap e, and to said electrode is metallically connected the battery-wire g, as shown. H is a yielding The electrode H is attached to or forms a part of a downwardly-projecting metallic rod h, connected in a suitable manner to the gascock so that the electrode I-I shall close and break contact with the stationary electrode G at the time the gas is turned on by the said gas-cock, and thus automatically ignite the gas and air compound by electric means when turning on the gas.

' In the drawings, Figs. land 2, I have shown the gas-cock I as provided with four ports 2',

adapted to close and open the gas-passages a K, and on the stem of said gas-cock is loosely hung a spring-actuated lever L, to which is pivoted the pawl-lever M, having a pawl 1n, adapted to engage the ratchet or pawl-wheel K in turning on or off the gas, as is common in electric gas-lighting devices.

The lower end of the rod 71. is pivoted to the lever L, as shown in Figs. 1 and 2.

Iwish to state that Ido not confine myself to any particular mechanism for opening and closing the gas-supply or actuatingthe electrode H, as this may be done by other suitable mechanism without departing from the essence of my invention.

N is a cord orchain attached to the pawllever N for actuating the gas-cock, as is common in electric gas-lighting devices.

From theabove it will be seen the yielding electrode H will sweep by the stationary insulated electrode G when the cord N is pulled in opening the cock to turn on the gas to the burner, causing a spark to be produced between the electrodes, by which the gas is ignited within the burner F.

When the operator releases his hold on the pull-down N the lever L is automatically-returned by the influence of its spring to its normal position shown inFig. 1, causing the electrode H to again sweep by the electrode G, by which a secondary'spark is produced to light the gas in case the primary spark should have failed to ignite the gas.

The electrodes are located out of the flame when at rest, as shown. By this arrangement I am enabled to light incandescent Welsbach burners by electricity, thus obviating the difficulty of lighting such burners from the top or otherwise, as is now the case.

I have illustrated and described the sparking device arranged in the mixing-chamber,

consisting of a movable and a stationary electrode, as I deem this the best form of sparking device in practice; but I do not limit my invention to a sparking device consisting of a movable and a stationary electrode, as other known descriptionsiof sparking devices-are equally within the scope of my invention.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim 1. In combination with a Bunsen burnerF having air inlets F and the incandescent mantle B suspended above it, a stationaryinsulated electrode G and a movable yielding electrode H arranged within the mixing chamber of said burner, the latter electrode being connected for operation to a gas cook on the gas supply pipe substantially as and for the purpose set forth.

2. In combination with a Bunsen burner F having air inlets F and the incandescent mantle B suspended above it, a stationary insulated electrode G and a movable yielding electrode H arranged within the mixing chamber of said burner and adapted to break and close the circuit for the purpose of igniting the gas within the said burner below its mantle, substantially as specified.

3. In combination with a Bunsen gas burner having gas and air supplies and a mixing chamber connected to such supplies, a stationary insulated electrode and a movable yielding electrode both arranged within said mixing chamber, substantially as and for the purpose set forth.

4. In combination with a Bunsen gas burner having gas and air supplies and a mixing chamber connected to such supplies, of a sparking device arranged within such mixing chamber, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 1st day of March, A. D. 1895.
